lies and then no response

Ref: Classic Campaigns, business account. Cell phone number ********** 166. I received my new phone by courier but my present simcard did not fit although the sales person had assured me it would. I had to buy a new one that cost me R70.00 to say nothing of the inconvenience. I have since then tried repeatedly to get a refund but after 12 emails and 14 phone calls to the help line, have had no response. I keep getting pushed to another department.
